  • Patent number: 10115488
    Abstract: The present invention provides passive safety equipment, comprising: a cooling part formed to cool a first fluid, which is emitted from a reactor coolant system or a steam generator, and a second fluid in a housing; and a circulation induction sprayer which is formed to spray the first fluid emitted from the reactor coolant system or the steam generator into the cooling part, has at least part thereof open to the inside of the housing such that the second fluid flows thereinto according to a drop in pressure caused by the spraying of the first fluid, and sprays the second fluid with the inflown first fluid.

  • Publication number: 20180061514
    Abstract: The application provides a self-diagnosis and accident-handling unmanned nuclear reactor, which: can passively cool down excessively generated heat without an operation of an operator when a malfunction of the nuclear reactor has occurred, wherein a cooling operation for safety measures can be carried out in a completely passive manner without a separate control command by a change in environmental conditions such as the structure and pressure of the nuclear reactor; and has a simpler structure compared to that of a conventional nuclear reactor safety system. It also provides a self-diagnosis and accident-handling unmanned nuclear reactor, which performs heat exchange by using a two-phase heat transfer mechanism, wherein heat exchange performance is maximized by introducing a spray-type heat exchanger having an optimized structure in which channels are three-dimensionally arranged, and can also easily and passively control heat exchange without a separate control means by using saturated steam pressure.
